Big Think

Big Bang nucleosynthesis, the primeval formation of the universe's light elements such as hydrogen and helium, is now being studied with precision-cosmology methods, according to a science commentary drawing on Ethan Siegel's Big Think column. As measurement of the cosmic microwave background and element abundances sharpens, the earliest of the Big Bang's four cornerstones can be tested against observations with unprecedented accuracy.

A new essay argues that today's intellectual and personal predicaments are the product of four centuries of history: Descartes' division of mind and matter, the rise of the scientific method, and what the author calls the immense cost of introspection. The piece suggests that scaling up that 'cocktail' over time has produced the exact reality people now face, blending science history with reflection on how we think about ourselves.
